I bought a drumhead from Tomar industries - which looks awesome - problem is the instructions for wiring are for 2 rail operations.
I think this is probably obvious, but I want to take hot (+) from the center roller of the passenger car truck, and common (-) from the truck frames - correct?
If I want to take power from both rollers (i.e. from front and rear trucks to avoid dead spots), should I wire in series or in parallel?
Just want to make sure I don't get this wrong and ruin the small LED (note LED comes with resistor and rectifier which I will wire in before connecting to pickup rollers)
